Juliboo

Hello people ^^ I want to soon make a project with Hexxit, but I wanted to ask how that is so with copyright and such stuff. Allow modders to record a with the mods or rather not? Have the modders written that possibly somewhere and I'm just too stupid to find it? xD I hope you know an answer ^^ That would help me a lot I am German and my English is a little rusty ^^ I hope you can read it anyway: D ~ Juliboo
